♦ Mature and very well respected AGM and GEL technologies for valve-regulated lead-acid batteries ranging from 2Ah to 3000Ah





GEL battery Specific Features:
♦Rechargeable Gel Deep Cycle Battery
♦Gelled electrolyte made by mixing sulfuric acid with silica fume
♦The electrolyte is gel like ,immobile and does not leak ,enabling uniform reaction of each part of the plate .
♦High rate discharge performance due to tight assembly technology
♦Strong heat dissipation and wide operating temperature range 
♦Avoid acid mist being separated out , environment friendliness
♦Efficient venting system release excessive gas automatically
